Last week, President Obama became the latest public official to question expanded self-defense laws such as Florida’s stand your ground statute. Speaking at a press conference on Friday, the president challenged the law, asking if it really contributed to “the kind of peace and security and order that we'd like to see.”

Opponents say that stand your ground laws promote vigilantism and undermine public safety, while supporters say they empower law abiding citizens. So which is it? This week on Intersection, we’ll take a closer look at expanded self-defense laws.
